New York’s vaccine mandate has crippled the FDNY and put ambulances out of service. Now Biden is being warned that his illegal vaccine mandate is risking a national shutdown on a much larger scale.

In an interview, the American Trucking Associations’ executive vice president for advocacy Bill Sullivan told POLITICO that some companies may simply decide that the cost of the mandate is not worth the government’s checks. Sullivan said he has raised concerns to the White House, Office of Management and Budget and other executive branch officials. He noted that if companies drop their contracts, it may be harder to get certain foods to troops, transport fuel for military vehicles, or even deploy the National Guard.

That’s going to make it harder to replace workers fired because of the mandate with the National Guard.
